Murray,
I called him about a year ago to ask some questions about lenses listed on his site... he said he had not been keeping the site updated. It is possible that he decided that maintaining the it wasn't worth the effort, and may have let his domain name registration lapse (by intent or by mistake - as it easy easy to forget - The Washington Post did this week...).

Sounds like if he is going to update it, it will be at it's own pace. And maybe the renewal was done by someone or a 'bot that 'steals' expired domain names and hold them hostage to resell back to the forgetful owner...

I did try his 800 # I found on Usenet, but no answer at 5:10 PM. Maybe he only answers between 9 and 5 (?)
